6 / 10 page DC Characteristics for ’AC Family Devices (Continued) Note 2: All outputs loaded; thresholds on input associated with output under test. Note 3: Maximum test duration 2.0 ms, one output loaded at a time. Note 4: IIN and ICC @ 3.0V are guaranteed to be less than or equal to the respective limit @ 5.5V VCC. ICC for 54AC @ 25˚C is identical to 74AC @ 25˚C.
